Quicksand (also known as sinking sand) is a colloid consisting of fine granular material (such as sand, silt or clay) and water. It forms in saturated loose sand when the sand is suddenly agitated. When water in the sand cannot escape, it creates a liquefied soil that loses strength and cannot support
A Psamment has no distinct soil horizons, and must consist entirely of material of loamy sand or coarser in texture. In the World Reference Base for Soil Resources (WRB), most Psamments belong to the Arenosols. However, Psamments of fluviatile, lacustrine or marine origin belong to the Fluvisols. Psamments cover 3.4% of the global land mass.
Dry quicksand is loose sand whose bulk density is reduced by blowing air through it and which yields easily to weight or pressure. It acts similarly to normal quicksand, but it does not contain any water and does not operate on the same principle. Dry quicksand can also be a resulting phenomenon of contractive dilatancy.
Clorox brand bleach. Bleach is the generic name for any chemical product that is used industrially or domestically to remove color from (i.e. to whiten) fabric or fiber (in a process called bleaching) or to disinfect after cleaning. It often refers specifically to a dilute solution of sodium hypochlorite, also called "liquid bleach".
A variety of food colorings, added to beakers of water. Food coloring, color additive or colorant is any dye, pigment, or substance that imparts color when it is added to food or beverages. Colorants can be supplied as liquids, powders, gels, or pastes. Food coloring is commonly used in commercial products and in domestic cooking.
Brilliant blue FCF (Blue 1) is a synthetic organic compound used primarily as a blue colorant for processed foods, medications, dietary supplements, and cosmetics. [1] It is classified as a triarylmethane dye and is known under various names, such as FD&C Blue No. 1 or acid blue 9.
It is commonly known in a dilute aqueous solution as bleach or chlorine bleach. [4] It is the sodium salt of hypochlorous acid, consisting of sodium cations (Na +) and hypochlorite anions (− OCl, also written as OCl − and ClO −). The anhydrous compound is unstable and may decompose explosively.
Usual flour bleaching agents are: . Organic peroxides (benzoyl peroxide); Calcium peroxide; Chlorine; Chlorine dioxide; Azodicarbonamide; Nitrogen dioxide; Atmospheric oxygen, used during natural aging of flour
